Abstract
The utility model discloses an automatic barring gear of a fan, which comprises a motor, a barring motor control cabinet, a speed reducer, a universal coupling and an overrunning clutch. The barring gear disclosed by the utility model is provided with the motor; the lower side of the motor is provided with the barring motor control cabinet; a rotating shaft of the motor is connected with an input shaft of the speed reducer; the speed reducer is also connected with the overrunning clutch through the universal coupling; the overrunning clutch is provided with an inner check ring and an outer check ring; the inner check ring is connected with a main shaft of the fan; the outer check ring is connected with the universal coupling; and the inner check ring and the outer check ring are connected through a wedge block. After the motor of the barring gear is started, the inner check ring is driven by the outer check ring of the overrunning clutch, and simultaneously, a rotor of the whole fan is driven to rotate, and thereby, barring is successfully finished. The automatic barring gear of the fan has a simple structure and full-automatic operation, is time-saving and labor-saving and is capable of effectively improving the working efficiency and the stability of the fan.
Description
Technical field
The utility model belongs to mechanical field, relates to a kind of barring gear, is specifically related to a kind of blower fan automatic barring gear.
Background technique
In traditional fan starting process, the blower fan of and don't frequent start and stop bigger for rotary inertia, one section of lengthening on main shaft adopts artificial manual jiggering usually, coils fan rotor and rotates, and opens main motor again.This method is used till today always, and its shortcoming is: the each unlatching of blower fan all needs artificial execute-in-place, and also needs special tool(s) just can carry out manual jiggering, and this mode is operated more loaded down with trivial details, and efficient is lower.
The model utility content
The model utility purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of simple in structure, easy to operate blower fan automatic barring gear to be provided.
Technological scheme: blower fan automatic barring gear described in the utility model, its objective is such realization: the blower fan automatic barring gear, comprise motor, the jiggering motor controlling cabinet, speed reducer, universal shaft coupling, clutch, on the described barring gear motor is installed, the motor downside is provided with the jiggering motor controlling cabinet, the input shaft of described shaft of motor and speed reducer links to each other, described speed reducer also connects by universal shaft coupling and clutch, clutch is provided with inside and outside back-up ring, the main shaft of inner ring and blower fan links, outer ring and universal shaft coupling link, and Internal and external cycle links to each other by voussoir.Behind the motor start-up of barring gear, by the outer ring drive inner ring of clutch, drive the rotor rotation of whole blower fan, thus the jiggering success.
As preferably, described clutch is a free wheel device.
As preferably, in the described jiggering motor controlling cabinet time relay is installed, after auto-barring finishes, jump the tramcar motor of stopping quotation on the exchange automatically.
Universal shaft coupling described in the utility model plays the effect that connects retarder and free wheel device, and certain flexible compensation is arranged, the decentraction when remedying both sides main shaft installation.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the trouble that need use the artificial execute-in-place of particular disk turner tool when the utility model has solved the conventional fan jiggering, the blower fan automatic barring gear that provides is simple in structure, full-automatic operation, time saving and energy saving, can effectively improve the working efficiency of blower fan.
Description of drawings
Accompanying drawing is the utility model example structure schematic representation;
Embodiment
The utility model is described in further detail below in conjunction with specific embodiment:
Embodiment
Blower fan automatic barring gear as shown in drawings, comprise motor 1, jiggering motor controlling cabinet 2, speed reducer 3, universal shaft coupling 4, free wheel device 5, motor 1 is installed on the described barring gear, motor 1 downside is provided with jiggering motor controlling cabinet 2, in jiggering Electric Machine Control 2 cabinets time relay is installed, the rotating shaft of motor 1 links to each other with the input shaft of speed reducer 3, speed reducer 3 also connects by universal shaft coupling 4 and free wheel device 5, free wheel device 5 is provided with inside and outside back-up ring, the main shaft 8 of inner ring 6 and blower fan links, outer ring 7 and universal shaft coupling 4 link, and Internal and external cycle links to each other by voussoir 9.
Behind the motor start-up of barring gear,, drive the rotor rotation of whole blower fan simultaneously by the outer ring 7 drive inner rings 6 of free wheel device 5, thus the jiggering success.After the success of barring gear jiggering, open main motor, the rotating speed of main motor is greater than 1 rotating speed of motor in the barring gear, when rotating speed reaches general more than 100 when changeing, voussoir 9 breaks away from, thereby inner ring 6 and outer ring 7 are separated, at this moment, fan rotor drives 7 idle running of free wheel device inner ring, stops along with stopping of motor in the barring gear 1 in outer ring 6.The complete smooth starting of blower fan master's motor simultaneously, blower fan begins normal operation.
Claims (3)
1. blower fan automatic barring gear, comprise motor (1), jiggering motor controlling cabinet (2), speed reducer (3), universal shaft coupling (4), clutch (5), it is characterized in that: motor (1) is installed on the described barring gear, motor (1) downside is provided with jiggering motor controlling cabinet (2), the rotating shaft of described motor (1) links to each other with the input shaft of speed reducer (3), speed reducer (3) also connects by universal shaft coupling (4) and clutch (5), clutch (5) is provided with inside and outside back-up ring, the main shaft (8) of inner ring (6) and blower fan links, outer ring (7) and universal shaft coupling (4) link, and Internal and external cycle links to each other by voussoir (9).
2. blower fan automatic barring gear according to claim 1 is characterized in that: described clutch (5) is a free wheel device.
